Studs do work on ice For many of us who live in more temperate regions, the likelihood of a midday thaw followed by an overnight freeze means that ice may be frequently encountered Whether off-road or on-road this is where studs come into their own They are not failsafe, & you still need to treat ice with due respect, but studs do offer a big improvement in control to the extent that you can easily be lulled into a false sense of security, only to slip straight onto your backside soon after stepping off the bike Studs are available as off-road tyres with wide spaced lugs, or on road tyres with a much closer spaced tread It should be noted that compared to regular tyres, there is increased rolling resistance (making pedalling harder), & the studs can be pretty noisy on bare roads In climates where snow & ice persist through the winter, riders would tend to use studs throughout the season, whereas in regions such as the UK where ice is a more sporadic event, a quick change of tyres or even better a spare set of wheels made up ready seems to be the more efficient approach.
